Hello

I'm using jsclr together with extjs and today I found strange issue

Basically dropdowns in ExtJs does not work as expected and everything started working fine as soon as I removed the jsclr (concretelly Compile() method) from the project

of course I cannot do that (hope there is another way) so I started to inveestigate what compile is doing

It seems to be definyng .NET classes in C# and additionally it seems to overwriting existing objects ( concretelly date, array) those two seems to be problemtic one

Just to give me some pointers can you describe what exactly Compile is doing in few words and what it does with existing methods/objects

Thanks

Zdenek

Hi Zdenek,

If you're able to create a small html/js sample that reproduces this issue I can take a look at it. jsclr isn't supposed to overwrite existing types, only to extend them. The best way would be to reproduce this in a small sample and debug it. Can you create such a sample?

Cheers

D.

Hello

I cannot attach files here ( for some reason it hangs, so I'm copypasting html file below

you need

1. replace link to jsclr.js on line 15

then to reproduce my problem

1. display the page, type "alb" into the combo - you will see states filtered, delete "al" and type something else for example "t". Combo will stay empty

2. comment out "Compile()" call

repeat one - and you will see that after "al" and then changing to "t" the texas will be displayed. So Compile must influence something

thanks for help

var change = function (value) {

return Ext.String.format(template, (value > 0) ? "green" : "red", value);

};

var pctChange = function (value) {

return Ext.String.format(template, (value > 0) ? "green" : "red", value + "%");

Hi Zdenek,

Thanks for sending a great reproduction.

I found the culprit, seems that there was some function added on array called 'filter', which overrode the real one. I've updated the code on github, please grab jsclr.js from git and try again.

https://github.com/SharpKit/SharpKit-SDK/blob/master/Frameworks/JsClr/res/jsclr.js

Let me know how it goes.

Cheers

D.
